SPECIFICATION forming part of Letters IPatent No. 680,812, dated August 20, 1901. Application filed July 18, 1900. Serial No.23r995. (No model.)

To ctZZ whom it may concern:

Be it known that I, MIOHAELSHERIDAN, a citizen of the United States, residing at the city of New York, borough of Manhattan, in the county and State of New York, have invented certain new and useful Improvements in Disinfecting Apparatus, of which the following is a full, clear, and exact specification.

My invention relates to improvements in apparatus for dispensing and discharging disinfecting and deodorizing fluids into the atmosphere by means of compressed air; and said invention has for its object more particularly to provide a neat, compact, simple, and noiseless apparatus adapted to be operated by a door or analogous object by means of which a small quantity of fluid will be automatically discharged into the atmosphere from a suitable atomizing device whenever said door or other object is operated. The object above set forth I am enabled to attain by means of my invention, which consists in the novel details of construction and in the combination, connection, and arrangement of parts, as hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, wherein like letters of reference indicate like parts, Figure 1 is a side view showing the upper portion of a door and a lintel with an apparatus constructed according to and embodying my invention applied thereto. Fig. 2 is a top view thereof,

showing in dotted lines the doorpartly openedQ.

Fig. '3 is an enlarged front view of the apparatus detached from the lintel. section taken on the line 4 4 of Fig. 3, showing in dotted lines the piston-rod as being just released; and Fig. 5 is a general view of a door and frame completely equipped with my improved apparatus.

In said drawings, A designates the lintel of a door-frame, and A the upper portion of a door which is hinged at its right-hand side to the post A Upon the front of the lintel A adjacent to the post A is secured the apparatus B, consisting of the base 0, upon the left-hand end of which is mounted a pump-cylinder C, having a nipple a at its base, adapted to receive one end of a tube or pipe a, which is con- Fig. 4 is a nected at its other end to a suitable atomizing device a attached to a receptacle a containing the fluid to be atomized. lVithin the pump-cylinder 0 Works a piston D, having a piston-rod D secured thereto and extending through the head of the cylinder O, and Within said cylinder 0 and surrounding the piston-rod D is disposed a distended coilspring D adapted to maintain the piston D normally adjacent to the base of said cylinder 0. The projecting end of the piston-rod D is scarfed, and to the rear of said scarfed end is provided a notch or recess Z2 and the downwardly-projecting guides c c, which contact with the surface of the base 0 and prevent the rotating of the piston D and rod D within the cylinder 0.

In front of the cylinder 0 are arranged the parallel longitudinal guides or rails E E, which are mounted slightly above the base (1 in supports (1 d, and between the guides or rails E E is a block F, having its end facing the head of the cylinder 0 beveled.

G denotes a carriage supported upon and having the ends of its vertical sides loosely surrounding the guides E E, so as to permit of said carriage being reciprocated upon said guides E E. At the inner end of said carriage G is supported a shaft II, having projecting arms I I at its ends, provided with hooks e e, and 5 denotes a detent secured to the shaft II between the arms I I and provided with a depending support or leg J, and K K denote coil-springs or resilient bands, the outer ends of which are secured to hooks ff, projecting from the base of the cylinder 0 adjacent to the base 0, and their inner ends secured to the hooks e e of the arms I I, whereby to hold the detent J in engagement with the end of the piston-rod D and to retract the carriage G after the detent J has released the end of the piston-rod D.

Upon the base C near its right-hand end is secured a pulley L, and near the upper edge of the door A is secured an upwardly and forwardly projecting arm M, and N denotes a flexible connection, of leather, cord, &c., one end of which is secured to the free end of the arm M, and its other end after being passed over the pulleyL is secured to the carriage G.

The operation of the apparatus is as follows:

If we assume the apparatus and the door to be in the position indicated at Fig. 1, then as soon as the door is opened the arm M, being secured thereto, will in being moved away from the lintel A cause the flexible connection N to draw the carriage Gr away from the end of cylinder 0, and the detent J on said carriage, which is in engagement with the end of the piston-rod D, to partly withdraw the same from the cylinder 0. As soon as the support J rides up upon the beveled end of the block F the end of the detent J will be raised and its connection with the end of the piston-rod D broken, whereupon the piston D and rod D will be retracted to their former position by the action of the spring D and thereby expel the air from the cylinder 0 by way of the nipple (t and pipe at and operate the atomizer a After the connection between the piston-rod D and detent Jis broken the carriage G will continue to travel upon guides E E until the same reaches the ends thereof, by which time the door will have been opened to its farthest extent. With the closing of the door, the tension on the connection N being relieved, the carriage G will by the action of the springs K K be returned to its initial position, and the detent J caused to again engage the end of the piston-rod D, and thus render the apparatus ready for a repetition of the operation above described.

It will be observed that the carriage G is permitted or caused to travel after the detent J, carried thereby, has released the end of the piston-rod D. The object of this is to permit the piston D, which returns rather slowly owing to its being opposed by the aircushion produced in the cylinder 0, to be forced fully home by the spring D and thus prevent the carriage from being jammed against the end of the piston before this has had the opportunity to occur.

It will of course be understood that the apparatus herein shown and described may be operated by other means than a door. A closet-lid or hinged platform will serve the same purpose, and where any of these means are not convenient or desirable the apparatus may be operated by hand.

Without limiting myself to the details of construction,which may be varied within the scope of the invention, what I claim, and desire to secure by Letters Patent, is
